Pump Pressure (measured in bar)
In pump performance, 1.0 Bar is generally considered low pressure, 1.5-2.0 Bar medium pressure and ≥3.0 Bar high pressure, eg. to run multiple showers/heads.

Single impeller pumps are generally used to boost the pressure of cold water supplied to a combi boiler (SSR, SSP or STP) or unvented cylinder (SSP or STP), whilst twin impeller pumps are used to boost the pressure of hot and cold water to a single shower (STR, SSP or STP), multiple showers or a whole domestic house system (Amazon).
A shower pump should be sited as close to the hot water cylinder as possible, however, if the shower pump is fitted in the loft or above the hot water cylinder (minimum static head required), please see Pump Location tab for example installations.
